A geometric spectral theory for n-tuples of self-adjoint operators in a finite von Neumann algebra: II
Charles A. Akemann, Joel Anderson
Given an n-tuple {b_1, ..., b_n} of self-adjoint operators in a finite von Neumann algebra M and a faithful, normal tracial state tau on M, we define a map Psi from M to R^{n+1} by…

Locally Minimal Projections
Charles A. Akemann, Joel Anderson
Given an n-tuple {a_1, ..., a_n} of self-adjoint operators on an infinite dimensional Hilbert space H and a positive integer k, there exists a projection p of rank k such that, for…

Regularity of projections revisited
Charles A. Akemann, Soren Eilers
The concept of regularity in the meta-topological setting of projections in the double dual of a C*-algebra addresses the interrelations of a projection p with its closure, for ins…
